Configuration of the connected sensor type
The sensor type of the sensor connected to "Input 1" of terminal X6 can be configured as follows:
• Parameter p4600
• Service menu: MAIN MENU > General setup > Special parameters > Function Input 1
Note that, internally, some signals (e.g. ESPE and LB) are logically ORed (corresponding to the
depiction in the "Sensor signals" figure). If the signal logic is configured for ESPE or SR, the
TestOUT function test signal is generated automatically.
An ESPE* can be connected to the SIDOOR ATD4xxW control units.
* according to DIN EN 61496-1:2013: Safety of machinery - Electrosensitive protective
equipment – Part 1: "General requirements and tests"
Take into consideration the following:
• ESPE of type 2 usually have PL c
• ESPE of type 3 usually have PL d
• ESPE of type 4 usually have PL e
• The resulting overall PL, for example, is to be determined according to EN ISO 13849-1: 2015
Section "6.3 Combination of SRP/CS to achieve an overall PL" (series connection subsystems:
sensors, switchgear if applicable, ATD4xxW):
– For type 2 ESPE, the resulting PL is maximum PL c (limitation by light curtain)
– For type 3 or type 4 ESPE, the resulting PL is maximum PL d (limitation by ATD4xxW)
The following figure schematically shows the interconnection of a type 2 ESPE with the SIDOOR
ATD4xxW control unit:
